GUN.

SPECIFICATION forming part of Letters Patent No. 505,006, datedSeptember 12, 1893.

Application filed March 2, 1893.

To all whom it may concern.-

Be it known that I, RUDOLF SAUER, manufacturer, a subject of the King ofPrussia, residing at Suhl, in the Kingdom of Prussia and German Empire,have invented new and useful Improvements in Guns, of which thefollowing is a specification.

My invention relates to improvements in guns or in the connection ofgun-barrels with the breech piece.

The connection of gunbarrels of any caliber with the breech piece iseffected according to my invention in such a manner, that undercutdovetail shaped ring segments turned in the gun barrel engage incorresponding grooves formed in the arcs of circles transverse to thelongitudinal axis of the breech piece and thus hold the barrel in a firmand secure manner. The two connected parts may be united with softsolder but solely for the purpose of preventing moisture frompenetrating between the said two connected parts. The subject of theinvention is illustrated in the accompanying drawings as applied to adouble barreled gun in Figures 1 to 3 and to a triple barreled gun inFigs. 4 and 5.

Fig. 1. is an elevation of the breech end of a double barreled gun. Fig.2. is a longitudinal section of the chamber portion thereof. Fig. 3.illustrates the breech piece thereof showing a barrel in position on theleft side. Figs. 4 and 5 show the connection of the breech piece with atriple barrel, in the connected and disconnected conditionsrespectively.

In Figs. 2 and 3 the letter Z indicates the left hand, and the letter Zthe right hand barrel, each of which is provided with dove-tail ringsegments 1", 1" formed in the arcs of circles transverse to the lengthof the barrel and nearly but not completely over the half of theperiphery of the barrel. The breech piece 11 is bored out to form abarrel-seat of conical form to correspond to the conical shape of thebarrel, and this barrel-seat is constructed with two dovetail-shapedgrooves s and 3, whose width and depth correspond exactly to thedimensions of the rings 7' and r. The breech piece 1; is provided in theusual manner with a hook or catch it and extended mid- Serial No.464,427. (No model.)

rib w. The connection of the barrels with the breech-piece is effectedby inserting the conical portion of the barrel into the accuratelyfitting recess 0 of the connecting piece 0 in such a manner that theperipheral surfaces of the rings 0". r engage in the grooves 8. 8'. Byrotating the barrel, the rings a". 0" become firmly fixed in the rings3. s.

In order to prevent moisture from penetrating between the barrel and theconnecting piece, and thus to prevent the formation of rust, the barrelsmay be soldered over with soft solder but such asoldering is notrequired in view of the strong joint made by a" s 1" 8'.

Figs. 4 and 5 illustrate the application of my invention to a triplebarreled gun. In this case the connecting piece 0' at the lower barrelis solid.

For fixing the other two barrels m and m there are again two grooves sand s (Fig. 5) formed in each of the left hand and right hand conicalrecesses c of the breech o which are however only continued up to themiddle of the recesses in order not to weaken the wall of the underlyingbarrel. Consequently the dovetail-shaped undercut rings a" r on the gunbarrels are also only provided for about one quarter of the periphery ofthe barrel.

The fixing is effected in exactly the same manner as just described withor without soldering. A fixing of this kind of the barrels to thebreechpiece is perfectly secure and has the advantage that inconsequence of the undercut rings of the connecting piece the solderingis not liable to be strained. Overheating of the barrels in solderingwith hard solder is consequently excluded and thus warping or bending ofthe barrels is obviated. Furthermore every damaged barrel can bereplaced in a most simple and easy manner. Also the breech pieces ofsteel can be made completely finished and interchangeable before beingconnected to the barrel, because said breechpieces are not located withthe range of fire.

Having now fully described my invention,

what I claim, and desire to secure by Letters transversely to thelongitudinal axis of the In testimony whereof I have hereunto set breechpiece, with abarrel having a dove-tail my hand in presence of twosubscribing witring segments formed in the arc of a circle nesses.

transverse to the length of the barrel and RUDOLF SAUER. adapted to beengaged with the groove by Witnesses:

axially rotating the barrel, substantially as WILHELM BINDEWALD,
